AARON KERRY, OF SEATTLE, WASHINGTON.

HORSE SHOE To all whom it may concern:

Be it known that I, r ARON KERRY, citizen of the United States, residing at Seattle, in the county of King and State of \Vashing ton, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to horseshoes.

The objects of my invention are the improvement in calks of the detachable type and to perfect the manner or means for securing the same to the shoes; and consists in the novel construction and adaptation of devices as will be hereinafter described and claimed.

In the drawings, Figure 1 is an underside view of a horseshoe adapted to the present invention and illustrated as unprovided with the toe attachments. Fig. 2 is a fragmentary like View with the toe attachments applied thereto. Fig. 3 is a front elevation of Fig. 2. Fig. 4; is a cross section taken through (0-46 of Figs. 2 and 3. Figs. 5, 6 and 7 are detached perspective views of the shoe attachments illustrated in Figs. 2, 3 and t illustrative of the preferred manner of carrying out my invention. 'Figs. 8 and 9, respectively, are underside and front elevational views of a portion of a shoe provided with the invention in a modified form. Figs. 10 and 11 are detached perspective views of the shoe attachments shown in Figs. 8 and 9.

The reference numeral 1 designates a shoe of suitable shape to fit the foot of a horse and is provided at its toe with a recess 2. Located in the longitudinal axis of the shoe and in proximity to the tee is a screw-threaded aperture 3 and to the rear of the latter is a hole 1, while to each side of the aperture 3 are holes 5. The holes 1 and 5 need not all be included in a shoe but, to accommodate either of the two forms of attachments which will be presently described, they are desirably provided so that such attachments may be used interchangeably.

The preferred manner of carrying out the invention is illustrated in Figs. 2 to T, inclusive, of the drawings, and will be first described: The calk, as shown in Fig. 6, is comprised of a block 6 provided at its ends with upturned lugs 7 and has a centrallydisposed screw-stud S which extends upwardly for engagement in the shoe-aperture 3. 9 is a plate having a rectangular bend at 10 to furnish a web 9 and a flange 9.

Specification of Letters Patent.

width of the web at its juncture with the flange corresponds to that of the shoe recess 2 and from thence rearwardly the web-sides l1 diverge toward the rear edge 12 which is of less width than the distance between the calk lugs 7 while the thickness of the web is somewhat less than the heights of such lugs. Said web is provided with an aperture 13 and an upwardly projecting pin 1): which are respectively arranged to register with the aperture 3 and the hole at of the shoe. Two wedges, such as 15, see Fig. 7, are provided for securing the calks in place. Each of these wedges are formed in proximity of its smaller end to have a shoulder 15 whence protrudes a tongue 15.

To assemble the aforedescribed parts, the plate 9 is first placed against the underside of the shoe with the flange 9 thereof within the shoe recess 2 and the pin l-i inserted in the hole t. The stud 8 of the calk is then introduced through the plate aperture 13 and, by properly rotating the calk, is screwed into the shoe aperture 3 until the ealk-lugs 7 are brought to bear against the shoe and in such rotary position that the calk-body will be disposed transversely with respect to the shoe. The calk being thus positioned, the wedges are driven from the front into the cavities intermediate the edges 7 of the calk-lugs and the opposing edges 11 of the web whereupon the tongue 15 of each wedge is turned over upon the rear edge 12 of the plate, as represented .in the right hand wec ge in Fig. 2.

The construction of the various members, as shown in Figs. 8 to 11, inclusive, differs from the aforedescribed embodiment of the invention in various particulars. The calkbody 16, as best: shown in Fig. 10, instead of having lugs at its ends is provided integrally therewith with a central longitudinally disposed bar 17 and has a screw stud 18 which projects upwardly. The plate 19 in this instance (Fig. 11) is provided with a web 20 having dowmvardly extending lugs 21 at its ends which are arranged to have their inner edges 21 converging toward the rear, see Fig. 8. These lugs 21 protrude from the under face of the web to a greater extent than the thickness of the calk bar 17. The width of the plate web is approximately that of the calk-body to serve as a bearing for the ends of the latter, consequently, and in order to withstand the excessive tendency to turn from shocks encountered by the calk, two

pins 22 may be and desirably are provided to engage in the shoe-holes 5.

To assemble the members of the last described embodiment of the invention, the plate 19 is first placed against the bottom of the shoe so that the flange 20 will extend through the recess :2 and the pins 22 engage the holes lVhereupon the stud 18 of the calk is entered in the aperture 25 of the plate member and screwed into the aperture 8 of the shoe until the calk-body 16 bears against the lugs 21 of the member 19 and in the position in which it is illustrated in Fig. 8. The wedges 15 are then driven in and their tongues turned over the end of the call: bar as at the right in Fig. 8.

In both of the aforedescribed methods of carrying out the invention the call; body is borne at its ends either against the shoe directly or against the intermediately positioned plate. In each case such plate is positively secured to the shoe against rotation through the otfices of the plate flange and the pin, or pins, respectively engaging in the shoe recess and hole, or holes, and cooperates with the wedges to maintain the calks in their set positions. The calks being borne only at their ends afford sufficient flexibility at their midlengths to allow the calks being forcibly rotated into operative position. To remove the calks the wedges are first driven out by blows delivered upon the shoulders 15 thereof, when the call: may be turned to unscrew its stud from the shoe, whereby the plate is released for removal.

What I claim, is

l. The combination with a horseshoe hav ing a recess at the toe and provided with a screw-threaded aperture, of a plate having a flange adapted to seat in said recess for locking the same against rotation, a call; provided with a screw stud for engagement with said aperture, and locking means which coacts with the plate and the calk for preventing the rotation of the latter.

2. The combination with a horseshoe, of a callr, a plate interposed between the calk and the shoe and engaged with the latter against rotation, screw devices for securing the calk to the shoe, and locking devices between the plate and the call: for securing the latter against rotation.

3. The combination with a horseshoe provided with a screw-threaded aperture, of a plate, means provided upon the plate to engage the shoe against independent rotary movements, a call: provided with a screw stud to engage in said aperture, and locking devices engaging the plate and the calk for preventing the calk from rotating with respect to the plate.

4. The combination with a shoe provided with a screw-threaded aperture and a pinreceiving hole, of a plate provided with downwardly extending lugs in proximity of its ends, a pin on the plate adapted to engage in said hole, a calk having integral therewith a centrally arranged bar and a screw stud arranged for engagement in said aperture, and wedges adapted to secure the calk against rotation with respect to the plate by engagement between the said bar and the respective lugs.
